The invention relates to a method for processing the inorganic surface of nanometer zinc oxide, and belongs to the field of nanometer materials. The method for processing the inorganic surface of the nanometer zinc oxide comprises the following steps: cladding aluminum phosphate on the surface of the nanometer zinc oxide; then cladding silicon oxide; filtering and washing the paste of the nanometer zinc oxide, so that the electric conductivity of filtrate is less than 300 Mu S/cm; drying the filtrate; and obtaining nanometer zinc oxide composite powder after the filtrate is crushed. The method has short process flow, convenient operation and easy control. The nanometer zinc oxide composite powder prepared has the advantages of excellent light stability, small dissolution rate of zinc ion and good dispersivity.
